Gastric lipoma causing gastroduodenal intussusception.

A case of gastroduodenal intussusception caused by a submucosal gastric lipoma in a 48-year-old man is presented. He had intermittent symptoms of regurgitation and heartburn for a period of three years. Barium meal and CT scan showed a mass in the first part of duodenum. At laparotomy there was intussusception of gastric antrum into the duodenum with a submucosal lipoma in the antrum which formed the apex of the intussusception.
